Frigidaire Dishwasher Error ER — What It Means & How to Fix It

What Does This Error Mean?

Error ER means the electronic control board in your Frigidaire dishwasher has detected a communication problem — it is not getting the expected signals from one or more components. This can be caused by a power surge, a loose wiring harness, or a failing control board. A power reset fixes ER in many cases, but if it returns repeatedly the wiring or control board needs inspection.

Common Causes

Power surge or voltage fluctuation corrupted the control board's memory
Wiring harness connector has come loose from the control board or a component
Control board has partially failed and is misreading component signals
One of the sensors (thermistor, water level) has failed and is sending garbled data
Moisture or condensation has gotten into the control board housing

How to Fix It

Turn off the dishwasher and cut power at the circuit breaker. Wait a full 10 minutes — longer than a typical reset — then restore power.

A longer power-off period fully discharges the control board's capacitors and is more effective than a 1-minute reset for ER errors.
Run a short wash cycle. If ER does not return, a power surge was the likely cause. Consider plugging the dishwasher into a surge protector if your model allows, or have an electrician check the outlet for voltage fluctuations.

Dishwashers in homes with unstable power or older wiring are more prone to ER errors.
If ER returns, open the control panel (inner door panel) by removing the screws around the door edge. Locate the control board and inspect all wiring harness connectors — press each one firmly to seat it.

Vibration from normal use can gradually loosen connectors, especially on older machines.
While the inner door panel is open, inspect the control board for burn marks, swollen capacitors, or signs of moisture damage.

Any visible burn marks mean the board has failed electrically and must be replaced — cleaning or reseating connectors will not help.
Check the thermistor and its wiring (see the E1 page for details). A completely failed thermistor can cause the control board to log an ER communication error.

Fixing an underlying sensor fault is cheaper than replacing the control board — rule out sensors first.
If all wiring checks out and ER persists, order a replacement control board for your exact model number. Install it by transferring the wiring harnesses from the old board to the new one.

Replacement Frigidaire dishwasher control boards typically cost $60–$120. Confirm your model number on the door jamb label before ordering.

When to Call a Professional

If a power reset does not clear ER, or if the code returns within a few cycles, you need to inspect the wiring harness connections on the control board — this requires pulling the dishwasher out and removing the inner door panel. If all connections are secure and ER persists, the control board itself is likely failing and will need to be replaced. Control board replacement is a job most homeowners can do with basic tools, but if you are not comfortable with electronics, a technician is the safer choice.

Frequently Asked Questions

Does error ER mean my Frigidaire dishwasher control board is broken?

Not necessarily — ER is a general communication fault and is often caused by a one-time power glitch or loose connector. Only if ER returns persistently after a reset and wiring inspection does the board itself need to be replaced.

Can a power surge cause error ER on my Frigidaire dishwasher?

Yes, this is one of the most common triggers for ER. A surge protector rated for appliances can help prevent future occurrences if power quality in your home is poor.

How much does a Frigidaire dishwasher control board replacement cost?

The part alone costs $60–$120 depending on your model. A technician will charge $180–$300 total for diagnosis, parts, and labor.
